GEORGE S. BLAKESLEE, OF OAK IRK, ILLINOIS.

WASHING MACHINE.

Application led August 1G, 1920. Serial No. 403,759.

To @ZZ whom t may concern:

Be itv known that I, GEORGE S. BLAKESLEE, a citizen of the United States, and a resident of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing Machines, of which the following is a specific-ation, reference being had to the accompanying drawings.

My invention relates to washing machines, and particularly to machines intended for washing metal parts, such as castings. SuchA parts vary greatly in size and weight, and are of a great variety of shapes, many of them being quite irregular, so that it is a diiiicult matter to provide a machine which will operate with certainty to handle such articles Without damaging them, while at the same time they are eHectively cleansed. Economy of space is also an important consideration, and it is highly desirable that a washing machine of this character be so constructed as to have great capacity for the space which it occupies. To provide a washing machine which will meet the above mentioned requirements is the object of my present invention. I accomplish this object as illustrated in the accompanying drawings andv as hereinafter described. What I believe to be new is set forth in the claims.

In the accompanying drawings,-

Fig. 1 is a side elevation of my improved machine;

Fig. 2 is a partial horizontal section thereof, showing that half of the machine adjacent to the inlet end thereof;

Fig. 3 'is a similar view showing the discharge end portion of the machine, both Figures 2 and 3 being taken substantially on line 2-2 of Fig. 1; v FFig. 4 is a vertical section on line 4-4 of Fig. 5 is an end view of the discharge end of the machine; and A Fig. 6 is a detail, being a partial horizontal section on line 6 6 of Fig. 1.

My improved machine comprises an elongated tank, which in the best embodiment thereof is divided transversely midway of its length to form compartments for washing and rinsing water; paddle wheels disposed laterally with reference to said tank and operating respectively in the washing and rinsing compartments to thro7 water therefrom ing and rinsing compartments, the conveyor y in the Washing compartment being arranged to deliver the articles carried thereby to the conveyor in the rinsing compartment; and a rotary reticulated cylindrical member eX- tending longitudinally over the tank above said conveyors, in the best embodiment of said invention said cylindrical member being arranged to operate also as a conveyor for conducting comparatively small articles through the machine while they are subjected to the action of the washing and rinsing water. In order that such cylindrical member may operate as a conveyor, it is provided with a spiral core extending 1ongitudinally through it so that as said member rotates the articles contained in it will be advanced therethrough and discharged at the outlet end of the machine. All these operating parts are connected for operation by a single motor, and the usual piping is provided for supplying hot water to the washing and rinsing compartments, and for drawing oii the water therefrom when desired. i

Referring tothe drawings-7 indicates the tank as a whole, 8 the washing compartment, 9 the rinsing compartment, and 10 the partition which separates the tank into said two com artments. 11 indicates the paddle whee associated with the washing compartment, and 12 the paddle wheel assol ciated with the rinsing compartment. These paddle wheels are mounted in lateral -eX- tensions 13, 14 of a housing 15, which encloses the operating parts of the machine and which is an extension of the tank proper. The two paddle wheels have their aXes alined and are mounted on a common shaft 16, as shown in Fics. 1, 2 and 3, so that they rotate in unison. Said shaft is driven by an electric motor 17, preferably mounted on a platform above one of the paddle Vwheel housings, as shown in Fig. 1. The armature shaft of said motor carries a pulley 18 which is connected by a belt 19 with a pulley 20 mounted on a countershaft 21, as best shown in Figs. 1 and 3, This countershaft carries a spur pinion 22 which meshes with a gear 23 mounted on the shaft 16, as just shown in Fig. 1. As best shown in Fig. 4, the lower portions of the paddle wheels 11, 12 dip into the water inthe lateral extensions of the tank 7 and the blades of said paddle wheels are arranged so that when said wheels rotate in the direction indicated by the arrow in Fig. 4 they take up the water and throw it laterally into the upper portion of the washing kand rinsing compartments.

24, 25 indicate endless conveyors mounted respectively in the washing and rinsing compartments, and arranged to conduct articles to be washed in the same direction over the water in said compartments. rllhese conveyors are in the form-of endless chains which operate over sprocket wheels, the conveyor 24 being supported and actuated by sprocket wheels 26, 27, and the conveyor 25 by sprocket wheels 28, 29, a's shown in Fig. 1.'

The sprocket wheel 26 is mounted on a transverse shaft 30 suitably mounted near the inlet end of the Washing compartment,and the sprocket wheels 27 and 28 are mounted respectively upon transverse shafts 31, 32 mounted in the housing at opposite sides near the upper end portion of the partition 10, as best shown in Fig. l, from which it.

will be `'seen that said partition extends up between the shafts 31, 32 and terminates below the level of the upper loops of the two conveyors 24, 2 5. rlhe shafts 31, 32 project outside of the housing at one end, as shown in Fig. 6and their projecting ends are provided with sprocket wheels 33, 34, respectively, whichv are connected bya link belt 35, as best Lshown in Figs. 1 and 6.- Thus the two conveyors operate in unison and their upper or operating surfaces move in the same direction. The sprocket wheel 29, which is located near the discharge end of the machine, is mounted on a transverse shaft 36 which also extends out through the casing and carries a sprocket wheel 37 over which travels a link belt38 connecting the shaft 36 with a shaft 39 having a sprocket wheel 40,. as best shown in Fig. 3. The shaft 39 also carries a worm wheel 41 with which meshes Ja worm or spiral gear 42 mounted upon an end portion of the paddle wheel shaft 16, as best shown in Figs. 1 and 3. By this construction the two conveyors 24, 25 are driven from the motor 17 through the I paddle wheel shaft.

rll"he construction of the conveyors 2 4, 25 is best'shown in Figs. 4, 5 and 6, from which it will be seen that each of said conveyors comprises flat transverse bars 43 secured intermediately of their length to the conveyor chains so that they are horizontally disposed and spaced a distance apart. rll`hese conveyore are designed to accommodate baskets or trays v44 in which the articles to be washed are placed, said baskets being preferably slightly less in width than the width of the main. portion of the tank 7, as indicated by dotted lines in Fig. 5, and they are long enough to rest on two or more of the cromacceso? i that they are not engaged by a basket 44 when the latter occupies a horizontal position, but should the basket tip its lower margin will strike the adjacent rail and will be prevented from tipping further.

lt will be apparent that a basket deposited upon the conveyor 24 at the inlet end of the machine will be carried along by said conveyor and automatically transferred at the center of the machine to the conveyor 25, which will conduct it to the outlet end of the machine, and that as the basket passes through the machine its contents will be subcylinder 47 which extends longitudinally of' the machine over the washingand rinsing compartments and over the conveyors 24, 25. rll`his cylinder may be either wire mesh or any other l suitable openwork construction which will permit Water to pass therethrough and will at the same time serve as a conveyor foi` comparatively sm all articles. lin the construction shown. said cylinder is provided with a 'central longitudinally-extending shaft `48 around which winds a spiral blade 49, as best shown in Figs. 2 and 3. lf desired the xshaft and blade may be made integral with each other. as shown in Fig. 4. rllhe shaft 48 and blade 49 are iixedly connected withv the cylinder 47 so that they rotate in unison. rll`he ends of the cylinder 47 are both open, and at the inlet end thereof a hopper or funnel 50' is provided through which the articlesto be washed are introduced. At the outlet end of the machine a Vtable 51 is provided to receive not only the baskets delivered by the conveyor 25, but also the articles delivered from the cylinder 47.

The cylinder 47 is rotated through the shaft 48 by means of a link belt 52 which runs over sprocket wheels 53, 54. rlhe sprocket wheel 53 is mounted' on one end portion of the shaftI 48, as shownin Fig. 2,

and the sprocket wheel 54 is mounted upon a shaft 55 which is driven from the paddle wheel shaft 16 through sprocket wheels 56, 57 and a link belt 58, the sprocket wheel 57 being mounted on the paddle wheel shaft 16, as best shown in Figs. 1 and 2. By this construction all the operating parts' are driven from. the motor 17. 59 indicates a loading table at the inlet end of the machine, as best shown in Figs. 1 and 2. 60, 61 indicate overiow pipes for controlling the level of the water in the washing and rinsing compartments.

It will be seen from an inspection of Fig. 4 that the lower portion of the cylinder 47 is opposite the upper portions of the paddle wheels 11, l2 and overlies the conveyors 24, 25, and as indicated by the arrow in Fig. 5 the lower portion of said cylinder moves in the opposite direction to that of the water thrown by said paddle wheels. When the lmachine is in operation, therefore, the water thrown by the paddle wheels will strike the lower portion of said cylinder while the same is moving in the opppsite direction, thus increasing the force of the impact of the water not only upon the surface of said cylinder but also upon the articles contained therein. A part of the wa- -ter will pass into the cylinder and will thoroughly scour the contents thereof, after which it will fall upon the articles carried by the conveyors 24, 25. Part of the water will also be deflected by the cylinder and distributed downwardly over the article carried by said conveyors. The result is that the articles carried by said conveyors, as well as those contained within the cy1inder 47, will be thoroughly scoured without waste of either water or time. Furthermore as the cylinder 47 occupies space which has heretofore been wasted, the capacity of the machine' is very largely increased without increasing the fioor space which it occu pies. My improved machine, therefore, is

peculiarly suitable for use in factories where the available space is limitedv and where a machine of large capacity is'required.

So far as l am aware I am the first in the art to provide a washing machine of the type described having a rotary member arranged to cooperate with the paddle wheel or wheels to direct the water upon articles traveling thereunder; or one in which suchrotary member is in the form of a reticulated cylinder which operates also as a conveyor to conduct articles to be washed through the machine. I also believe myself to be the first to provide a washing machine of the character described with a plurality of conveyors arranged in different horizontal planes. These features are, therefore, claimed generically. In other respects also my invention is not limited to the specific construction shown and described except in so far as the same is particularly claimed.
